[Q] Sim Card Compatablity

So heres a question. When i talked to the sales rep they said i would be getting a new sim card. So if thats the case is the new card compatable with my current Tilt 2 phone (HTC Rhodium) since the Inspire is not a world phone?

A sim is a sim. As long as the phone is compatible with the network and not locked(or on its locked carrier) it should work fine. They reused my Captivate sim.

When I got my phone they gave me sim it looks different form the 3g sim. the pattern on the back is changed so you can get the 4g frequency

Yeah, they gave me a new sim, they said it was for the 4G

A new SIM is not required for HSPA+. Any change you see is purely coincidental.

This is absolutely correct you don't need new sims

heck, they put the 'cingular' sim in the inspire from my krazr and it works fine.

The sim card i am using is from my old tilt 2. They just moved it from my old phone into my new Inspire working great.

Sounds like the sales rep you dealt with was a confused. New sim cards have been released for LTE, but they are not supposed to be activating them until the old sim cards are depleted.

AT&T has released a new batch of SIM cards that will support HSPA+ and future LTE devices. I have attached a image of what the new SIM looks like. You will not notice any difference between the new SIM's until you begin using LTE devices in 2012.

The Inspire is not a world phone? It won't roam overseas??

G2X won't recognize SIM card

Anyone else experience issues with swapping their SIM from their old phone into the G2X? I have reseated mine from my N1 into the phone 3 times, and each time I boot it says I have no SIM card. Pulling my hair out!

I went from an N1 to the g2x and i had the same problem so here is the deal...
the g2x is a 4g phone and it required a new sim card version so i had to trade in the sim card that i have had since my i got my razr in 2005...
so disclaimer to anyone who buys the phone outright, you have to have an updated sim card... just go into tmobile and they will give you one...

mines wont check for sim card at all it keep saying no service even without a sim card it usually say no sim but it just say no service can someone help plz plz plz

Fyi make sure it is a corporate store. Otherwise it could cost ya $20. Customer care might even be able to mail you one...not sure. If your near Chicago I would just give you one of my extras.

I reused the sim from my N1 and have had no issues but it was probably a newer version sim since I just got it beginning of last year.

If you have an old T-Mobile phone lying around, try inserting your SIM into that, and using it, then re-insert it into your G2X.

Alright I opened it up and it looked like the antenna cable was a bit frayed near the tip, I attached a few pics. It was connected though so not sure :/

I have the same issue.
Mint condition G2X does not detect my sim card reads "error while trying to connect to network"
I am running CM 7.2 I have wiped everything and reflashed still no luck.

Add one more to the pile...
I also recently began having this problem, but my device previously worked fine.
I have tried Restoring to Factory V21Y with Mar 11 Baseband
Flasing a GB Based ROM & Stock Kernel
Flashing CM9
Flashing CM10
Entering *#*#INFO#*#* Phone Info and modifying frequency band (No Go).
At one point I was able to read the Phone # from the SIM card, but couldn't get a lock on Netowkr. I can visually detect T-Mobile and ATT in Mobile Networks.
I have tried this with 4G Enabled SIM Cards and older T-Mobile SIM Cards.
I have tried Simple Mobile, Straight Talk, & ATT SIM Cards.
I have tried using None APN's, the TMo/Simple Default APN's, and Modified APN's for Straight Talk & Family Talk.
No avail.
Any ideas?

I had the same problem. A new SIM card fixed it.

I gave my friend my old G2x because she was switching from AT&T to TMobile. She went to the TMobile store and got a new SIM card and her old AT&T number transferred to it. It works on her old iPhone but when I insert the SIM card on the LG G2x , it keeps saying 'no SIM card inserted'....do i need to flash a certain baseband on it and/or setup a custom APN for it? I am on the stock ROM thats rooted...
Any help is much appreciateed

Sorry for not replying until now but I rarely visit here anymore. My G2X had a bad Sim card which a new Sim fixed. I just had to wait until the network could authorize with it.

MT4GS on AT&T

What do folks know about the MT4GS on the AT&T network? I used the Sensation exploit to sim unlock the phone. Got the code, entered it and it says network unlock successful but I can't get it to connect to the AT&T network once I insert the AT&T sim. I attempted to add the AT&T apn settings to the MT4GS but they won't save. I have a network unlocked MT4GS and an AT&T sim card.
Can anyone offer any advice?

Is your sim card activated? And have the proper data plan?
You need to go to the att store and have it activated and then have the towers updated.
Thats what my brother in law just told me who works at att. He said you can call them as well.
I actually have an att sim he gave me thats active, but needs to be paid, so i couldnt test it. I used it to unlock the phone.

When i had plenty of tmobile androids on att i never had to tell them, and i dont understand why they would update towers. Make sure you hit menu and select save in apn settings

I have an idea. Go to settings, wireless and network, mobile network settings, then network operators, click search and select att.

Love you all are weighing in so quickly to help me think about this problem. XDA really is the best. I've tried all the things suggested and still no luck. I just had a thought that I'd like to run by you all. The phone is 4g. Do I need a 4g sim card from AT&T? The sim card is active. It's moving from an unlocked T-Mobile Vibrant to this unlocked T-Mobile MT4GS. So I know that the sim card works and can be used in an off-network device. But I don't know much about 3g/4g and sim cards. The current plan is 3g data on AT&T.
The problem is that the MT4GS behaves as if the sim isn't even there. I can put in a Simple Mobile sim and it fires right up. I can put the AT&T sim back into the Vibrant and it works right away. So how do plans work with sim cards?
If it is a 3g plan will the MT4GS not even see the sim card?
You guys rock.

It could be. make sure the sim is in right way and it isnt badly damaged. Since simple mobile works it leads me to think the sim is having an issue of some sort.
I would try getting a new sim from att with a 4g plan, see if that works. If im not mistaken, theyre free, if you get a paid plan.

You will not get 4g on the slide, so you don't need a 4g card. Differing spectrums. Vibrant gets 3g on ATT but its the only one.

Doesnt att and t mobile use hspa+ or ++? I was under the impression tmobile leases the same nodes att uses
sent from my RuBiX infused MT4G Slide using xda premium

After you enter the new AT&T APN settings make sure you hit the menu key to actually save the APN settings. Just hitting the back button well NOT save the settings at all. I'm using the MT4GS with my AT&T account and everything works great. Although you well NOT get 4g or even 3g, you well get 2g.

Sent from my Sensation_ReMiX using Tapatalk

Just wanted to confirm it's working here too. AT&T sim (it's a 4G sim, from my SGS2) in a sim-unlocked myTouch 4G Slide running Bulletproof 1.something. APN had to be entered manually, but I didn't have to manually tell it to use AT&T.

The issue was Cyanogenmod. I don't know why or how but once I flashed Bulletproof 1.1 it took the AT&T sim fine. I reflashed CM in order to verify and it wouldn't take the sim again. I don't know. After flashing Bulletproof 1.1, I used the Tweakker app (an app I wish could be included in every rom) to get my AT&T APN settings and everything worked from there. Thanks everyone for the troubleshooting help. I don't know why it seems to have issues with our CM rom and the AT&T sim card.
The phone is, as we all know, limited to the edge network while on AT&T. Thanks peeps.

[Q] rooted with custom rom cant activate to new number

I left sprint recently sold my phone with it rooted and and a patched ota rom on it. The guy went to get it activated and they couldn't get it done, said it was freezing up, sprint rep knew it was rooted, and said it needs to be back to stock unrooted???? Is this true? Anybody know?

Any time you take your phone to sprint ALWAYS UNROOT. They can tag the account. You should of unrooted before selling the phone

They were probably trying to get into the Activation Menu in ESPT. If they could not get it to work, that would be a clue that the phone was Rooted. But as mentioned in the post above. As a Rule of Thumb, never sell a phone Rooted. Also never take a phone into a Sprint store for any type of Tech work if it's Rooted. They can and most times do Flag the account. Not what you want. After that any phone issues you run into they may try to claim it's because your device is rooted.

Thanks I put it back to stock.
I didn't realize a rooted phone would not allow you to get into the "Activation Menu in ESPT"
You can get more money some times for rooted phones, but i guess not with Sprint. My bro sold a SGSII rooted for T-mobile for big bucks, but i guess with sim cards, it makes it easy.
Is the "Rule of Thumb" to return phones back to stock before selling for Sprint and Verizon phones only?

I'm sorry, I didn't properly explain. Rooting doesn't affect if you can get into ESPT or not. Rooted phones can still use ESPT without issue. But it does depend on the Rom on the phone. But yes as a " Rule of Thumb " , if the device is going to be Sold or taken in for service. No matter who the person, or carrier is it's always better if it's Unrooted.

Not to be rude but Verizon uses CDMA (like Sprint excluding Nextel products that use iDEN). Verizon phones domestically do not use sim cards. The only CDMA phones that use sim cards are dual mode international phones (the sim card is only used for GSM networks abroad). AT&T and T-mobile use sim cards domestically (GSM) so maybe one of those?

Thats not entirely true. LTE uses sim cards. Any Verizon phones with 4G will have a sim card.

Actually, from what I have read on the internet, Verizon LTE SIM cards are tied to activation of 3G CDMA on LTE equipped phones. I don't know how they did it, though. Also, I heard that Verizon LTE devices have the PRL loaded on the SIM card making it nearly impossible to flash a different PRL onto the phone. I even heard that Sprint is doing that with their LTE phones.

Please help!

Hi guys.
I have a question. I bought a Motorola Atrix 4G (original carrier is ATT). The original owner tried to unlocked the phone with an unlock code that she bought, but some how the phone kept giving the "SIM network unlock PIN" screen. I have tried with 3 three different active SIM cards, even an ATT SIM card, i still can't get the phone to work on any of the networks.
So, is it possible to root or unlock the phone so it will work with any GSM SIM cards? I want to use it on Tmobile. But right now it's not even working with the original carrier (ATT). I appreciate any suggestions/ comments.

I solved the problem by reflashing the frequency
